Synopsis

The chapter reveals that a training dungeon has transformed into an 'enclosed dungeon,' a much more dangerous scenario where the exit disappears and all monsters must be defeated to escape. The instructors, aware of the severity, plan to use recruits as meat shields, while the protagonist recognizes a surge of demonic energy, a sensation from his past experiences, and eagerly confronts the source. The instructors and some recruits are incapacitated by the demonic energy, and the protagonist's sudden charge into danger leaves the others stunned and concerned.
